> Currently, when a ProcessSession is committed, the Content Claim that was 
> being written to is now "finished" and will never be written to again.
> When a flow has processors that generate many, many FlowFiles, each in their 
> own session, this means that we have many, many files on disk on the Content 
> Repository, as well. Generally, this hasn't been a problem to write to these 
> files. However, when the files are to be archived or destroyed, this is very 
> taxing and can cause erratic performance.
